Answer:
0.08m/s²
Step-by-step explanation:
Acceleration is a rate, a rate of Velocity over Time. To measure it you have to know how fast someone, or something in this case sprints at a given interval of time.
t1=30 V1=3m/s
t2=40 V2=3.8m/s
So, with all data collected. Let's calculate it:
[tex]a=\frac{V_{2} -V_{1}}{T_{2}-T_{1}}=\frac{3.8-3}{40-30}\\ a=0.08m/s^{2}[/tex]
a=Δv/Δt
a= 0.08 m/s²
At 0.08 meters per square second the sprinter accelerates over a ten seconds period.
